Thanks Joe Does Make Sense , Car Has Chassis Rail Connectors , 6 Cyl Torsion Bars , Good Shocks As Well , Car Has Done A Lot Of Slow 2.01 - 2.05, But It Has Done 1 - 1.9 60 F/t , Would Like To Go Down To 4:11 Gears Still Want Driveability . . .
2.0 is bad, but i understand driveability, it really comes down to what you want from the car, like wild said, the .557 solid will have better manners over the .509, but i don't think you'll see much ET gain to justify the aggravation of changing things over, if you keep working & dialing in the tune, that .509 will have decent street manners as well, i've run a few of em & really liked them, even though there an older design.
